Amazon offers the Bose SoundTrue On-Ear Headphones in Purple/Mint, model no. 626237-0010, or Mint, model no. 626237-0020, for $79.99 with free shipping. That's tied with our expired mention from two days ago (of two other colors) and the lowest total price we've seen. (It's also a current low by $10, although most merchants charge $130 or more.) They feature a fold-flat design, detachable cable, in-line remote, microphone, memory foam ear cushions, and include a zippered carrying case.

Note that these headphones have an estimated shipping delay of two to four weeks.
